AI Technical Summary
Existing vehicle fixtures have poor stability when fixing wheel hubs, causing the wheel hubs to wobble easily during processing, which affects the processing quality.
A clamping and fixing mechanism is adopted, in which a motor drives a rotating rod to rotate a bevel gear, which in turn drives a screw to rotate. The screw then moves the clamping block and anti-slip pad toward the center of the wheel hub, achieving stable fixing.
This improved the stability of the wheel hub, prevented wobbling, and enhanced the processing quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel hub processing technology, specifically a wheel hub processing fixture. Background Technology
[0002] Lathe fixtures are fixtures used on lathes to machine the inner and outer rotating surfaces and end faces of workpieces. Wheel hubs are often machined on lathes, and fixtures are needed for positioning and clamping during the machining process, which requires the use of lathe fixtures.
[0003] Chinese patented invention CN211867166U discloses a wheel hub machining fixture, belonging to the field of wheel hub machining technology. The wheel hub machining fixture includes a worktable with a through circular hole on its left side. Multiple sets of adjustment grooves are formed on the upper surface of the worktable outside the circular hole. Sliding grooves are formed on both sides of the inner wall of each adjustment groove, and a locking device is provided between the adjustment groove and the sliding groove. The locking device includes a return spring, one end of which is fixedly installed on the inner wall of the adjustment groove away from the circular hole. The other end of the return spring is fixedly connected to a cross-shaped sliding block, and a convex elastic plate is fixedly connected to the other side of the cross-shaped sliding block. This invention, through the clamping device and the locking device, provides a double fastening effect, facilitating wheel hub machining operations, which is superior to existing technologies and convenient to use.
[0004] However, the device still has some problems. In actual use, the method of fixing the wheel hub by moving the convex elastic plate with the return spring has poor stability. When processing the wheel hub, the wheel hub is prone to shaking and deviation, which reduces the processing quality of the wheel hub. Therefore, we propose a wheel hub processing jig to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a vehicle clamp for processing wheel hubs, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub machining fixture, comprising a clamping and fixing mechanism, wherein the clamping and fixing mechanism comprises a base plate, a vertical plate, a screw, and a clamping block;
[0007] Three vertical plates are fixedly connected to the top of the base plate. A screw is rotatably connected to the outer side of each vertical plate. A round rod is threadedly connected to the outer side of the screw. A clamping block is fixedly connected to the end of the round rod. An anti-slip pad is fixedly connected to the outer side of the clamping block. The end of the screw extends to the outside of the corresponding vertical plate and is fixedly connected to a first bevel gear. Three rotating rods are rotatably connected to the top of the base plate. A second bevel gear is fixedly connected to the top of each rotating rod. The first bevel gear meshes with the corresponding second bevel gear.
[0008] More preferably, two square rods are fixedly connected to the outer side of the vertical plate, and two rectangular rods are fixedly connected to the outer side of the clamping block.
[0009] More preferably, the rectangular rod is slidably sleeved on the outside of the corresponding square rod, and the outer ear of the rotating rod is fixedly sleeved with a transmission roller.
[0010] More preferably, the outer sides of the three drive rollers are connected to the same belt.
[0011] More preferably, a circular support block is fixedly connected to the top of the base plate.
[0012] More preferably, a motor is fixedly connected to the bottom of the base plate, and the end of the output shaft of the motor is fixedly connected to the bottom end of one of the three rotating rods.
[0013] More preferably, each of the four bottom corners of the base plate is fixedly connected to a support leg.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor of this utility model drives the second bevel gear to rotate through the rotation of the rotating rod. The second bevel gear drives the screw to rotate through the rotation of the first bevel gear. The screw drives the corresponding clamping block to move through the movement of the round rod. The clamping block drives the corresponding two rectangular rods to move. The rectangular rods slide on the outside of the corresponding square rods. The clamping block drives the corresponding anti-slip pads to move. The three clamping blocks move towards the center of the hub. The anti-slip pads contact the outside of the hub and fix the hub. At this time, under the action of the screw, the hub is fixed, which has high stability and can stably fix the hub. When the hub is processed, the hub is not easy to wobble, avoiding deviation and improving the processing quality of the hub. Attached Figure Description
